FAN ATTACHM ENT.

SPECIFICATION forming part of Letters Patent No. 591,721, dated October 12, 1897.

Application Iiled March 13 1897.

To all whom it may concern.-

Be it known that I, ISRAEL S. BAILEY, residing at Farmers Branch, inthe county of Dallas and State of Texas, have invented a new and useful Automatic Fan, of which the following is a specification.

My invention relates to an automatic fan adapted for use in connection with rockingchairs or with cradles.

The object of myinvention is to provide an automatic fan which can be moved from place to place and easily attached or detached to a rocking-chair or cradle and which is adapted to be rotated as the chair or cradle is rocked.

My invention consists, essentially, of a fan the blades of which are hinged and which is adj ustably carried on a rod orshaft, the lower end of which reciprocates in a socket provided with a spiral groove, and having means in connection with the rod or shaft for clamping it to a rocking-chair or cradle.

My invention consists also of certain details of novel construction that will be hereinafter fully described, and specically pointed out in the claims.

In order that my invention may be fully understood, I will proceed to describe the same with reference to the accompanying drawings, in which Figure l is a perspective view showing my automatic fan connected to a rocking-chair. Fig. 2 is a detail perspective view of the fan. Fig. 3 is a detail sectional view of the socketpiece, showing the rod or shaft tting therein. Fig. 4 is a detail sectional view of the hub of the fan. Fig. 5 is a detail perspective View of the clamp by which the rod or shaftV is connected with a rocking-chair. or cradle.'

In the said drawings, A represents a rod or shaft carrying at its upper end ,the fan B and having its lower end provided with the tangs or projections C, which work in the spiral groove C, formed in the socket D. The rod is also provided with a screw-threaded portion E, on which the nuts E' work. The plate F is provided with the projections F', between which the end G of the clamp G' is hinged.

It will be understood that the opening in the plate is large enough to permit of a ro- Serial No. 627,302. (No model.)

tary motion of the shaft and that the nuts E are not clamped tightly against the plate F, v

so that as the chair is rocked the rod or shaft will be given a reciprocating motion, so that as it moves up or down in the spiral groove in the socket it will have a rotary motion back and forth, so as to operate the fan.

The fan B is composed of the hub B and the blades B2, which are hinged at B3, so that they may swing to Va horizontal position when rotated over the chair in front of the shaft.

To prevent the blades from swinging too low during the rear half of their rotation behind the chair, I provide the projections B4 on the hub, against which the free ends of the blades bear, and they are so arranged as to stop the blades when they form a right angle with the hub.

B5 represents a set-screw passing through the hub for adj ustably holding the fan on the rod or shaft A.

The socket D, which is provided with the spiral groove, is hinged to the weight H, and its lower end is rounded, so as to fit in the curved portion of the base H, which is of sufficient weight to anchor itself wherever placed, and has acurved recess on its upper face in which the curved lower end of socket D fits, and said lower end being hinged to the base and forming a knuckle-joint therewith. The use of this construction is to allow the socket to conform to the angle of the rod or shaft as the rod or shaft is reciprocated in the socket. Ihe spiral groove C is of such a pitch Vas to allow the tangs or projections to easily work in it, so that a rotary motion will be given the rod or shaft.

The operation of my device will be readily understood, as will be seen from the drawings.

The device is portable, and for that reason can be placed in such a position as to be out of the way when attached to a rocking-chair or cradle. Vhen it is to be attached, the

nuts E' are turned so as to allow the plate F to be moved up or down on the rod or shaft according to the height of the rocking-chair or cradle to which it is adapted to be applied. After it is clamped to the rocking-chair or cradle the nuts are turned close to but not so as to clamp the plate between them, thereby IOO causing,` the rod to move up or down as the cradle or chair is rocked. As the rod or shaft is reciprocated the projections follow the spiral in the socket and cause the shaft to be rotated and the fan to force the air downward upon the chair or cradle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the rod or shaft, the Weighted base, a clamp, adapted to be secured to a chair or cradle, a plate through which said shaft passes, a fan secured on said shaft, having its blades hinged at their inner, upper corners, and means for rotating the fan actuated by the rocking of the chair or cradle, substantially as set forth.

and below said plate, and a fan adjustably secured to the rod or shaft, substantially as set forth. v
